The Pac-12 Conference has fined Arizona coach Sean Miller $25,000 for his actions following the 18th-ranked Wildcats' loss to UCLA in the semifinals of the conference tournament.

The conference announced Sunday night that Miller was fined for confronting a game official on the floor and for acting inappropriately toward a staff member in the hallway.

Miller received a technical foul late in Arizona's 66-64 loss to No. 21 UCLA on Thursday for arguing that Wildcats guard Mark Lyons should not have been called for a double dribble because Bruins guard Jordan Adams touched the ball.

Miller apologized after the game for getting a technical so late in a close game, but added that he did not cuss or challenge the officials, and repeatedly said, "He touched the ball," for emphasis.
